I figured the original comment here was stating that there are airlines that aren't listed. (Kayak lists AirAsia and Garuda at least though.)
For one comparison that hurts:

vs:

(Although clearly if one were actually going to Sumatra, one would stay for more than 3 days...)
But you don't need to do something exotic like Bangkok <-> Sumatra to see a disparity. Even Bangkok <-> Singapore or Kuala Lumpur show problems.
